c. Drill a hole in the ceiling for wiring; pull all wiring through the hole and terminate all wires
(if not already terminated).
NOTE: You do not have to run wiring through the ceiling; you can fasten the wires to the ceiling
and then run the wires through the gap between the ceiling and the surface mount ring (refer
to Figure 5).

3. If you are wiring more than one dome drive to the same transformer, connect one side of the
transformer to pin 9 of the RJ45-10 connector on all modules. Connect the other side of the
transformer to pin 10 of the RJ45-10 connector on all modules.
NOTE: Failure to connect all modules identically may produce a vertical roll when switching between
cameras.
4. Connect your power wiring to the dome drive using one of the following options (refer to Table F on
page 16 for wiring distances):
• Plug the RJ45-10 connector on the end of the supplied interface cable (refer to Figure 6) into
the mating connector on top of the dome drive, and then connect your wiring to the other end
of the cable.
• Connect the supplied RJ45-10 connector to your wiring, and then plug the connector into the
dome drive.

5. Connect your video and data wiring to the dome drive using either an unshielded twisted pair (UTP)
of wires (refer to Table E on page 16) or coaxial cable (refer to Table D on page 16). A BNC connector
for coaxial cable is attached to the dome drive.
6. Attach the dome drive to the ceiling (refer to Figure 3 and Figure 4 on page 17).
7. Line up the tabs on the trim ring with the slots in the dome drive. Snap the trim ring and bubble into
place.
